Voltaren Gel. Thank me later. It became over the counter last year vs. Prescription. CVS, Walgreen‘s, Costco, etc. carry it. Works aLmost all joints/spine. Not good for fleshy areas (shoulder, hips). I was able to stop getting 3 spinal injections a year once I was turned on the Voltaren. In the US, it has 1% diclofenac (in the US the more ‘powerful’ gel at +2% still requires a prescription). I buy the more powerful across the counter when I’m in Mexico, Canada or Europe where the more powerful gel doesn’t require a prescription. Diclofenac is commonly found in anti-inflamatories like Bufferin, etc. I’m not a doctor so you may or may/not be interested in speaking to your GP about Voltaren. My mom used it on her joints until her passing at 94. G’luck. John
